IMPROVEMENT IN BOILER-CLEANERS.

Specification forming part of Letters Patent No. 194,723, dated August2B, 1877; application filed June 30, 1877.

To all lwhom 'it may concern Be it known that I, EZEA RANsoM, of Flint,in the county of Genesee and State of Michigan, have invented a new andvaluable lmprovement in Apparatus for Extracting Impurities from Waterin Steamoilers; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of a part sectional sideelevation of my apparatus for extracting impurities from water insteam-boilers, and Fig. 2 is a plan view of the same.

The nature of my invention consists in the construction and arrangementofan apparatus for extracting impurities from water in steamboilers, theobject being to take the scum from the surface of the water in that partof the boiler over the fire-box, and, by means of a pipe, carry itoutside of the boiler through a filter and back into the rear part ofthe boiler through a pipe connecting the lter with the rear part ot' theboiler.

The annexed drawings, to which reference is made, fully illustrate myinvention.

A represents a steam-boiler, with tubes or flues B B of any ordinaryconstruction. Within the boiler A are two floats, C C, connected by aplate, C', and ou this plate are bolts a, a, upon which are placed twosmall bars or plates, b b, adjusted up and down on the bolts, and heldat any height desired by suitable nuts ,or ordinary set-screws may beused for the same purpose.

The bars or plates b b are attached to two skimmers, D D, which are madein the form of bellows, and. their inner ends connected by a pipe, d.The skimmers being thus made adjustable they can be raised or lowered,so as to bring their mouths even with the surface of the water.

From the center of thepipe d a pipe, G, leads to and connects with ashort pipe, G1, passing through the top og' the boiler. In this pipe G1are three joints, e, e, and e1, which allow the floating skimmers toadjust themselves to the level of the water, rising or falling in theboiler by the working of the feed-pump; or, in`

locomotive-boilers, going around curves or up and down grades; or inmarine-boilers subjected to the roll ofthe ship.

h is a rod, passing down through the lug i, to keep the lioating skimmerin the center of the boiler. H is a lever, connected to the inner end ofthe pipe G, and hung on a rod in the boiler, the other end of the leverbeing provided with a counterbalancing-weight, I, for the purpose oflifting a portion of the deadweight of theA oats, skimmers, joints, andpipes, so that the skimmers can be set lower and still be on thesurface. This enables the skimmers to perform their ofce closer down tothe tubes or lines.

The upper end of the pipe G1 is, by a pipe, G2, connected with a ilter,J, outside ot the boiler. This lilter is provided with interiorpartitions m m', arranged as shown, whereby the current of water ispartially broken, the water rst passing up over the top of the partitionlm., thence down the Vcenter of the filter, where the impurities, beingheaviest, will settle, and the purified water passes up between thepartition 'm' and the shell of the filter to the outlet-pipe G3, throughwhich it passes back into the boiler.

The filter J is at the bottom provided with an outlet-pipe, K, whichshould have a stopcock to be opened when required, for drawing 0E allthe sediment out of the lter.

The pipes G2 and Gr3 are also to be provided with stop-cocks, for thepurpose of. stopping the circulation when required.

rlhe operation of the apparatus is as follows: The stop-cock in pipe G3being closed and that in the pipe G2 opened, a current of hot water,with the impurities contained therein, with steam, will be forced` vupthrough the skimmers and pipes G G1 Gf2 into the filter J and thenceinto that portion of the pipe G3 between its stop-cock and the filter.The stopcock G3 is then opened, when the filtered water will be carriedback into the rear part of the boiler, a partial vacuum being formed inthe pipes G G1 Grz by the condensation of the steam therein and thecoolingof the water, thus causing a continuous circulation of the waterfrom the front to the rear part of the boiler, and a removal of theimpurities.

Wha-tI claim as new, and desire to secure by Letters Patent, is-

1. The skimmers D D, adjustably connected to floats A, and by pipesconnected With a tilter outside the boiler, for the purposes herein setforth.

2. The lever H, with Vcounterbalancing- Weight I, in combination Withthe iioats, skimmers, and pipes connected with the filter, as and forthe purposes herein set forth. s

3. The joints e e e', formed in the pipe G, in combination with theskimmers and oats,

' substantially as and for the purposes herein set forth.

4. The combination of the floats, the skimmers, eounterbalancing-lever,jointed pipe, ilter, and connecting-pipes, al1 constructed and arrangedto operate substantially as and for the purposes herein set forth.

1n testimony that I claim the above I have hereunto subscribed my namein the presence of two Witnesses.

EZRA RANSOM.
